Description

Technical Field

[0001] The utility model relates to the field of ice breaking for power transmission lines, in particular to an ice breaking device for overhead power transmission lines. Background Art

[0002] When cold raindrops fall on objects with a temperature below freezing (0°C), rime is formed. If they condense on wires, the wires will be covered with ice. This is wire icing. If all wires within a range are covered with ice, this is line icing. As the ice increases, the weight of ice on wires, insulator strings and poles and the wind pressure increases due to the increase in wind-exposed area after ice. When the combined load of ice and wind exceeds the allowable value of the strength of the above components, the line will be damaged.

This ice-breaking process can automatically de-ice the power transmission line, greatly improving the ice-breaking efficiency of the power transmission line.

[0036] Furthermore, the driving mounting seat 1 includes a seat body 3 , a driving wheel 4 and a disassembly seat 5 .

Under the contact of the disassembly seat 5, the power transmission line is in close contact with the driving wheel 4. Finally, turn on the travel motor 7, and the driving wheel 4 moves along the power transmission line, thereby driving the ice breaking hammer 2 to break ice on the power transmission line.

[0041] The disassembly and assembly seat 5 includes a cover body 8 , a connecting rod 9 and a positioning wheel 10 .
